Procedure

Prepared according to the procedure of Example 367 C using (3-[5-(ethoxyiminomethyl)(1H-indazol-3-yl)]phenyl)-N-(4-fluorophenyl)carboxamide.2HCl (1.50 g, 3.15 mmol), N-amino-2-(dimethylamino) acetamide (1.2 g, 10.33 mmol) and sodium methoxide (1.8 mL of a 25% w/w in methanol) in anhydrous methanol (20.0 mL) with a reaction time of 1.5 days. Purification by flash chromatography on silica gel using 50% methanol in ethyl acetate afforded a solid which was dissolved in anhydrous methanol and treated with anhydrous hydrogen chloride gas for 10 min at 0° C. After stirring at ambient temperature for 5 min anhydrous ethyl acetate was added to precipitate the desired product which was collected on a sintered glass funnel, washed with methanol and ethyl acetate and dried under vacuum to give the title compound (267 mg, 50% yield) as a light yellow solid 1H NMR (DMSO-d6) δ 13.5 (br s, 1H), 10.5 (s, 1H), 8.5 (s, 1H), 8.2 (br d, 1H), 8.1 (d, 1H), 8.0 (d, 1H), 7.84 (dd, 2H), 7.75-7.6 (m, 2H), 7.2 (t, 2H), 3.6 (bs, 2H), 2.2 (s, 6H), ES-MS (m/z) 456 [M+H]+.
